why oversleeping is bad for your health



  • 1 Oversleeping can increase the risk of dying early

    A study shows that adults who sleep for less than 6 hours or more than 8 hours are at a higher risk of dying earlier than those who sleep between 6 and 8 hours. They are four times as likely to have their blood supply cut off to part of the brain.

  • 2 Oversleeping (more than 8 hours) is worse than undersleeping

    Prof Franco Cappuccio, professor of cardiovascular medicine at the University of Warwick conducted a study showing that 12% more of the short sleepers -followed up over time- died compared to medium sleepers; while 30% more of long sleepers died compared to them.

  • 3 Oversleeping can cause diabetes or obesity

    Studies show that too much sleep increases the risk of diabetes. A recent study also shows that people who sleep for more than 9 hours daily are at a higher risk of obesity by 21%.

  • 4 Oversleeping causes headaches

    Researchers have found that oversleeping can affect the neurotransmitters in the brain, including serotonin, causing headaches. This is found also in people who sleep longer during the day than during the night.

  • 5 Oversleeping can cause heart disease or strokes

    The Nurses' Health Study conducted a study showing that 38% of the 72,000 women diagnosed, who slept for 9 to 11 hours are at a higher risk for developing coronary heart disease. This is because of the increase in blood pressure or cholesterol.

  • 6 Oversleeping can be an underlying reason of hypersomnia, causing depression

    Oversleeping can be a reason of hypersomnia, a medical disorder which leads people to suffer from extreme sleepiness during the day and excessive sleep during the night. This condition can lead to anxiety, low energy, memory problems, and eventually depression (See also other reasons for depression)

  • 7 Oversleeping can be an underlying reason of pbstructive sleep apnea

    This is a sleep disorder that causes people to stop breathing momentarily during sleep, and disrupts the normal sleep cycle leading to an increased need for sleep. There are many ways to overcome this condition; it starts by knowing how to have a good night sleep.

  • 8 Oversleeping can cause inflammation

    Prof Shawn Youngstedt of Arizona State University carried out a study showing that oversleeping can cause a higher level of a protein called IL-6 in the blood, which can result in higher inflammation levels.

  • 9 Oversleeping can cause soreness and back pain

    Health Guidance reports that there is a relationship between back pain and oversleeping. The longer the sleep duration, the more the spine is vulnerable to staying longer in harmful positions.

  • 10 Oversleeping increases the risk of Alzheimer's

    Alzheimer's Association International Conference found that people who sleep for more than 9 hours are more likely to develop Alzheimer's at an early age. This is because too much sleep happens to be bad for the aging brain.

  • 11 Oversleeping leads to procrastination and less productivity

    Oversleeping causes grogginess (the feeling of dizziness and weakness), which leads to lack of energy and laziness. (See also other reasons that lead to procrastination)

  • 12 Oversleeping can cause sleep drunkenness

    This is a condition where the person feels caught somewhere between being awake and being asleep. Dr. Daniel Kripke, co-director of Scripps Clinic Sleep Center in La Jolla, California states that this condition is mainly suffered by people who catch up on sleep during the weekends.
